detailed parameter list or P values, please refer to the corresponding firmware release configuration
template of the related products.
When Grandstream Device boots up or reboots, it will issue request for configuration file named
“cfgxxxxxxxxxxxx”, where “xxxxxxxxxxxx” is the MAC address of the device, i.e.,
cfg000b820102ab”. The configuration file name should be in lower cases.
7.3 Firmware and Configuration File Prefix and Postfix
Starting from firmware version 1.0.8.16 for BT-100 phone Rev 2.0, adding prefix and postfix for both
firmware and configuration file is supported.
Firmware Prefix and Postfix allows device to download the firmware name with the matching Prefix
and Postfix. This makes it the possible to store ALL of the firmware with different version in one
single directory. Similarly, Config File Prefix and Postfix allows device to download the configuration
file with the matching Prefix and Postfix. Therefore multiple configuration files for the same device
can be stored in one directory.
In addition, when the field “Check New Firmware only when F/W pre/suffix changes” is set to “Yes”,
the device will only issue firmware upgrade request if there are changes in the firmware Prefix or
Postfix.
7.4 Managing Firmware and Configuration File Download
When “Automatic Upgrade” is set to “Yes”, Service Provider can use P193 (Auto Check Interval, in
minutes, default and minimum is 60 minutes) to have the devices periodically check with either
Firmware Server or Config Server, whenever they are defined. This allows the device periodically
check if there are any new changes need to be taken on a scheduled time. By defining different
intervals in P193 for different devices, Server Provider can spread the Firmware or Configuration File
download in minutes to reduce the Firmware or Provisioning Server load at any given time.
